mid-Trip Indication
Circuit protection, rapid fault location
and alarm capability are blended
together in the Airpax mid-trip
indication option. This option is
designed for automatic handle
movement to a middle position upon
electrical overload, allowing for easier
detection of the fault circuitand
minimizing downtime due to the
overload condition.
In the optional auxiliary switch
configuration, the switch allows an
alarm or signal to be forwarded when
the breaker trips and the handle
moves to the middle position. The
alarm can be disengaged by the
manual actuation of the handle to the
OFF position. Once the fault has been
corrected, the circuit breaker can be
reset to the ON position. The mid-trip
option is available in one, two or three
pole toggle handle packages and in
either standard panel screw or snap-in
mounting. Please see specification
tables of specific product for available
ratings.
Snap-In mounting
The snap-in mounting adapter allows for
simplified mounting of most IEL/LEL
toggle handle products. Prior to
shipment, the adapter is attached to the
circuit breaker during our final product
assembly, allowing you to securely snap
the unit into a rectangular panel cut-out.
This eliminates the need for panel
mounting hardware and associated
assembly costs.
Available for units up to three poles,
with or without an option handle
guard.
